Schlumbergera plant named ‘CARNEVAL BRAZIL’

ABSTRACT

A new and distinct  Schlumbergera  plant named ‘Carneval Brazil’, particularly characterized by large upright to vertical flowers; flowers which have petals which are red-purple (RHS N74A) and a light purple throat (RHS 75D); large quantity of flowers per plant; moderately vigorous growth rate and freely branching growth habit; and mucronate to lanceolatoid buds red-purple (RHS 71B) in color.

Latin name of the genus and species of the plant claimed: Schlumbergera truncata.

Variety denomination: ‘Carneval Brazil’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Schlumbergera plant, botanically known as Schlumbergera truncata (Haworth) Moran., commonly known as Thanksgiving Cactus, and hereinafter referred to by the cultivar name ‘Carneval Brazil’.

Schlumbergera (formerly Zygocactus) of the Cactaceae family, consists of 6 known species which are epiphytic cacti and native to Brazil. Common names for Schlumbergera plants include: Crab Cactus for the cultivar's claw-like phylloclade margin, Thanksgiving Cactus for cultivars which bloom in November, and Christmas Cactus for cultivars which bloom in December.

The new Schlumbergera cultivar is a product of a planned breeding program conducted by the inventor, Lau Lindegaard Rasmussen, in Fyn, Denmark. The objective of the breeding program was to develop a new Schlumbergera cultivar with excellent branching habit and large, upright flowers with a unique color combination.

The new Schlumbergera cultivar originated from an outcrossing made by the inventor, Lau Lindegaard Rasmussen, in 2000 in Fyn, Denmark. The female or seed parent is the Schlumbergera truncata ‘8596C’ (unpatented). The male or pollen parent is an unnamed, unpatented cultivar of Schlumbergera truncata. The new Schlumbergera cultivar was discovered and selected by the inventor as a single flowering plant within the progeny of the stated outcrossing in a controlled environment in 2002 in Fyn, Denmark, on the basis of its flower color and its freely branching habit. Plants of the new Schlumbergera are more upright and have a unique color combination of the flowers combined with healthy, glabrous green phyllocladia and excellent branching.

Asexual reproduction of the new Schlumbergera cultivar by phylloclade cuttings, followed by trial production batches, was first performed in January of 2003 in Fyn, Denmark, and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘Carneval Brazil’ which in combination distinguish this Schlumbergera as a new and distinct cultivar:

-   -   1. Large upright to vertical flowers;     -   2. Flowers which have petals which are red-purple (RHS N74A) and         a light purple throat (RHS 75D);     -   3. Large quantity of flowers per plant;     -   4. Moderately vigorous growth rate and freely branching growth         habit; and     -   5. Mucronate to lanceolatoid buds red-purple (RHS 71B) in color.

No plants of the female parental cultivar, Schlumbergera truncata ‘8596C’, are available to provide a detailed botanical comparison to plants of the new Schlumbergera truncata ‘Carneval Brazil’. Plants of the new Schlumbergera truncata ‘Carneval Brazil’ differ primarily from plants of the female parental cultivar, Schlumbergera truncata ‘8596C’, in the following characteristics:

-   -   1. Plants of ‘Carneval Brazil’ have a petal color combination of         red-purple which is lighter than the red-purple petal color         combination of plants of ‘8596C’;     -   2. Plants of ‘Carneval Brazil’ have a light purple throat which         is darker than the light purple throat color of plants of         ‘8596C’; and     -   3. Plants of ‘Carneval Brazil’ have broad petals, whereas plants         of ‘8596C’ have narrow petals.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new Schlumbergera ‘Carneval Brazil’, is the Schlumbergera truncata ‘Purple Dancer’ (unpatented, disclosed in EU-CPVO No. 2004/1246) in the following characteristics:

-   -   1. Plants of ‘Carneval Brazil’ have a petal color combination of         darker red-purple (RHS N74A) and a light purple throat (RHS 75D)         whereas plants of ‘Purple Dancer’ have a petal color combination         of lighter red-purple (RHS N74C) and a light purple throat (RHS         75D);     -   2. Plants of ‘Carneval Brazil’ have longer buds (about 4.5 to         5.0 cm in length), which are lanceolatoid to mucronate in shape,         and darker red-purple (RHS 71B) in color whereas plants of         ‘Purple Dancer’ have shorter buds (about 3.5 to 4.5 cm in         length), which are obovatoid to obtuse in shape, and lighter         red-purple (RHS 72D) in color;     -   3. Plants of ‘Carneval Brazil’ produce lighter green         phyllocladia (mature, upper surface: RHS 137B and immature,         upper surface: RHS N138B) whereas plants of ‘Purple Dancer’         produce darker green phyllocladia (mature, upper surface: RHS         136A and immature, upper surface: RHS 137C);     -   4. Plants of ‘Carneval Brazil’ are shorter (about 14.5 cm) than         plants of ‘Purple Dancer’ (about 20 cm); and     -   5. Plants of ‘Carneval Brazil’ are more wider (about 22 cm in         spread) than plants of ‘Purple Dancer’ (about 19 cm in spread).

DETAILED BOTANICAL DESCRIPTION

The new Schlumbergera cultivar ‘Carneval Brazil’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant.

The aforementioned photographs, together with the following observations, measurements and values describe plants of ‘Carneval Brazil’ as grown in a glass-covered greenhouse in Fyn, Denmark, under conditions which closely approximate those generally used in commercial practice. Plants of ‘Carneval Brazil’ are themophoto-periodic and will develop buds and bloom best under short day conditions (less than 12 hours of sunlight for a period of 4 weeks). Plants of ‘Carneval Brazil’ are grown under an average day temperature of 18° C. and an average night temperature of 16° C. Ambient light levels of +50 W m-2 were used and no growth retardants were applied when growing plants of ‘Carneval Brazil’.

Color references are made to The Royal Horticultural Society Colour Chart (RHS), 4^(th) edition, except where general colors of ordinary significance are used. The photographs and descriptions were taken during the fall of 2007 in Fyn, Denmark, when outdoor day temperatures averaged 8° C. and outdoor night temperatures averaged 6° C. The age of the plants described is about 40 weeks after cutting.
